Abstract
The disclosed invention is a method of recovering hydrocarbons by employing a seven well pattern comprising five horizontal production wells and two vertical injection wells. Four of the horizontal wells form the four sides of a substantially rectangular pattern with the fifth horizontal well aligned on a diagonal running between two opposite corners of the substantially rectangular pattern formed by the first four horizontal wells. Two vertical injection wells are approximately located near the center of the two substantially triangular patterns formed by the five horizontal wells.
